Nicoll Highway MRT station is an underground Mass Rapid Transit station on the Circle Line in Singapore. Located underneath Republic Avenue near the Kallang River, the station serves commercial and residential developments along Nicoll Highway such as the Golden Mile Complex and The Concourse. During its construction, a section of the tunnels and the segment of the highway above caved in on 20 April 2004, killing four people. Following an investigation, which found human error and organisational failures as causes of the collapse, the station was relocated. Alongside the other stations on Stages 1 and 2 of the Circle Line, Nicoll Highway station opened on 17 April 2010. Designed by ONG & ONG, the station is 21.5 metres (71 ft) deep and has a black and grey scheme. Nicoll Highway station features the public artwork Re-claiming the Peripherals by Khiew Huey Chian, consisting of four reliefs depicting wild plants, displayed over the platform doors (example pictured).
